Our model also connects with the asymmetric dark matter (ADM) scenarios. The energy densities of visible matter(VM) and dark matter(DM) in the universe are of the same order[1]}, [2]}, with
\(\Omega _{\text{DM}}/\Omega _{\text{VM}}\sim 5\) . This serves as a motivation to look for common origins of both sectors in cosmological evolution. Observationally the VM asymmetry is [3]}, [4]} of the order of \(10^{-10}\) . Thus, a common origin is expected to leave an imprint of this asymmetry also in the dark sector. This is the basis for the framework of Asymmetric Dark Matter [5]}, [6]}. Considerable subsequent developments for the ADM scenario can be found in [7]}, [8]}, [9]}, [10]}, [11]}, [12]}, [13]}, [14]}, [15]}, [16]}, [17]}, [18]}, [19]}, [20]}, [21]}, [22]}. Our framework is motivated by recent proposals of RHN\((N_1)\)  as the DM candidate  [23]},[24]}. Our model, with three new right-handed Weyl states \(N_i, i=1,2,3\)  is the same as \(\nu \) MSM with the addition of a singlet scalar \(\phi \) .
